There are several ways to cope with travel in countries where you do not speak the local language.

You can learn some of the local language and/or a regional language. It will rarely be practical to learn a language for a short trip, but bring a phrasebook! Learning the basics of pronunciation, greetings, how to ask directions, and numbers (for transactions) can be enough to fulfill nearly all the essentials of travel on your own, and can be a fun activity on long flights or bus delays.

While locals are generally understanding and do not expect foreigners to be fluent in their language, any attempt to speak the local language is generally appreciated, even if your vocabulary is restricted to some basic greetings and numbers, and your pronunciation is not very good. This applies even in areas where English is widely spoken.

Try any other languages you speak. Older Chinese often speak Russian, some Turks and Arabs speak good French or German, and so on.

When one or both players has limited skills in whatever language you are using, keep it simple! Keep sentences short. Use the present tense. Avoid idioms. Use single words and hand gestures to convey meaning.

If none of those work for your situation, you can just smile a lot and use gestures. It is amazing how far this can take you; many people are extremely tolerant.

It is also fairly common in things like negotiating a price to write down numbers or key them into a calculator for display to the other party.

Even in really out-of-the-way places, you should at least be able to find hotel staff and guides who speak the regional language well. English is unlikely to be much use in a small town in Uzbekistan, for example, but Russian is quite widely spoken.

Regional languages are often useful somewhat beyond the borders of their region. Some Russian is spoken in Northern China, some German in Turkey, and so on. In Uzbekistan, Persian could be worth a try.

English is very much a world language — it is spoken in many countries and widely taught as a second language — and it is possible to travel almost anywhere using only English and a broad smile.

The map below shows the percentage of English-speakers for various nations. Keep in mind, however, that English-speakers are not evenly spread over a country. In nations where English is not the primary language, English-speakers are more likely to be found in major cities and near major tourist attractions. In Japan, for example, there is a higher concentration of English-speakers in Tokyo and Osaka, but the percentage drops significantly when you travel to more rural parts, like Shikoku or Kyushu.

Nearly anywhere, if you stay in heavily visited areas and pay for a good hotel, enough of the staff will speak English to make your trip painless. Nearly anywhere, you can hire an English-speaking guide and translator--especially if you take care of it beforehand. Travelling this way may not be as cheap or as interesting as it could be, but it will be relatively easy.

For a business trip, paying for good hotels and guides or translators may be the best strategy; the convenience and ability to get things done are more important than cost. For a backpacker on a tight budget, this is not a good strategy; coping with language difficulties should be considered part of the adventure. Many travellers fall somewhere between; they may choose a hotel where English is spoken, but they will also have linguistic adventures in the markets.

English differs between its varieties and the variant of English used often depends on which among the US and UK had greater ties to the country in question. Our English language varieties article gives you an idea of where which variety predominates and some of the words that differ among variants of English.

A few English words may be understood anywhere, though which ones will vary from place to place. For example, "OK" and "bye-bye" are used in Chinese and many Chinese speakers also know "hello" and "thank you". Unless you are dealing with educated people, however, that may well be the extent of their English.

French words also turn up in other languages. "Merci" is one way to say "thank you" in Persian and in Bulgarian.

English idioms may also be borrowed. "ta-ta" is common in India, for example.

Abbreviations like CD and DVD are often the same in other languages. "WC" for toilet seems to be widely used, both in English and on signs, in various countries, though never in English-speaking ones.

Words from the tourist trade, such as hotel, taxi and menu, may be understood by people in that line of work, even if they speak no other English.

The word for peace, used as a greeting, is shalom in Hebrew, salaam in Arabic, selamat in Indonesian.

Even if you use the form from another language, you might still be understood.

Some loanwords may be very similar in a number of languages. For example, "sauna" (originally from Finnish) sounds similar in Chinese and English among other languages. Naan is Persian for bread; it used in several Indian languages, though the recipe varies.

The word for tea is approximately "chai" across most of Asia (Hindi, Russian, Persian, Turkish, ...), "cha" in standard Mandarin and Cantonese (albeit with different tones) and "teh" in the Minnan dialect and in Indonesian (in fact, the English word tea was derived from teh).

It is fairly common for language to be part of the reason for various travel choices.

Some travellers choose destinations based partly on the language. For example, an English speaker might choose to visit Malaysia rather than Thailand or Jamaica rather than Mexico because it is easier to cope with a country where English is widely spoken.

Others may choose a destination where a language they want to learn or improve is spoken; see Language tourism.

Still others may use language teaching as a method of funding their travel; see Teaching English.

Language is almost never the only reason for these choices, but it is sometimes a major factor.
